Trionic 8 ECU

Product information "Trionic 8 ECU"

Are you looking for a reliable and affordable solution for your 9-3II? Then a refurbished Trionic 8 could be the answer! We use the latest methods and technology to offer a fully refurbished Trionic 8 that works like new. Each of our remanufactured units has also been tested in real vehicles to ensure it works reliably and is in perfect condition.

Purchasing a remanufactured unit not only saves you money, but also protects the environment. The remanufacturing of electronic components reduces the need for new products and thus lowers the carbon footprint. Our remanufactured units are also available at a fraction of the price of new, meaning you can keep your car in tip-top shape without breaking the bank.

Our units are compatible with all model years and part numbers!
The important thing is that you pay attention to whether it is a front-wheel drive or all-wheel drive (XWD) vehicle.

In addition to the control unit, you will also receive a heat protection plate with silent bearings.
Due to the suboptimal mounting position, the control units are exposed to great heat and vibrations, which lead to damage in the long term.

Usually, we are always happy about new customers. However, it always has been our main goal to provide enthusiasts a possibility to maintain their vehicles for as low cost as possible and so keep their cars on the road. One of the most common issues we encounter are failing Trionic 8 ECUs.Many people ahead of us already recorgnized the subpar position of the ECU.Therefore, there are already products available on the market.However, prices for these range well beyond 100€, come with long shipment times and partially consist of unrecyclable materials like bakelite.Due to this we decided to create a cheaper and more environmentally friendly solution.Our first version consisted out of HDPE (High Density Polyethylen), which already offered high protection from heat radiation.However, driven by our constant demand of high quality products, we developed a new version together with our customers.The 2nd version therefore, consists of PTFE (Polytetrafluoroethylene; also known under its brand name Teflon™) and offers a much wider temperature resistance (-200 to +260°C),while also reducing the thermal conductivity from 0,38W/mK to 0,23W/mK.Instead of the reflective tape used in previous versions, we decided to utilize SILCAWOOL 120, which provides a thermal conductivity as low as 0,04-0,05W/mK at temperatures up to 200°C.You can therefore, rely on a high quality precision product and optimal protective properties.Content:- 1x Heat shield out of PTFE (back taped with SILCAWOOL 120P)- 1x Ground cable- 2x 20mm spacers- 3x M6x16 bolts- 1x M6x18 bolts- 4x Silentbloc bearings100% Made in Germany.UK buyers please click here.
